Important
Both the SC3 and SC4 chucks are made to very
tight tolerances to ensure extremely accurate
performance. On both chucks the permissible
axial run-out is 0.1 mm and the permissible
radial run-out is 0.15 mm. To ensure the chucks
perform as accurately as possible, the jaws must
be mounted correctly so as to minimise run-out.
Match each jaw with its corresponding slide and carefully
attach them as shown in Fig 8.13. Only loosely secure
the jaws so that some movement is possible.
Now close the jaws together fully and they will self-
centralise on the jaw slides and perform with optimum
accuracy. Tighten the screws to complete installation.
Once the jaws are attached to the chuck body, thread the
chuck onto the lathe spindle as previously shown.
Warning: Before turning any workpiece using
any method described in this manual, ensure the
timber is free from any cracks, splits or other
defects which may cause it to break apart
during turning. Also ensure that the workpiece
is securely held by the chuck before turning is
carried out.

Compatibility with Other Manufacturers’
Chuck Jaws
The RECORD POWER SC range is an exclusive system
designed to improve on the systems we sold previously.
However, to minimise any redundancy for customers of
the previously sold ‘RECORD POWER - NOVA Series’ G3
or Supernova 2 range, our improved system has been
designed to use the same jaw mount profile, making it
possible to still utilise jaws from the previous system
where required. However it is important to note the
following:
Safety
It is important that the mounting system described in
this manual is followed fully. If you follow the described
process but the jaws (from any manufacturer) do not
locate properly on the jaw slide, do not centre correctly
when fitted as per these instructions or will not tighten
